1989 420SEL No Power to Fuel Pumps
Engine would not start after shutoff from normal driving. No power to fuel pumps. Fuel pump relay and voltage overload relay have been replaced with no effect. Power is coming in to fuel pump relay. Is there any other relay/junction/etc between fuel pump relay and pumps?
Any advice/guidance will be deeply appreciated, love this car.

1983 300SD sudden "ticking" from engine
About two months after replacing the vacuum pump, a sharp "ticking" sound started that seemed to come from the front of the engine, and that varied directly with the engine speed. Checking the power steering pump reservoir revealed it was about half full. I added fluid but the ticking was still there.
The next thing I did was to adjust the valves. While turning the engine by hand for this procedure, I noticed a sharp-but-hollow sounding "pop" coming up from deep inside the engine at the timing chain. The sound occurred at what seemed to be every complete revolution of the engine. It may have been every half-revolution, but in any case, the "popping" was occurring at consistent points in the rotation of the engine. I know the vacuum pump opens up into the crankcase...

1983 300SD Glow Light Stays On
3 months ago I replaced all my glow plugs and used the reamer tool to clean out the carbon build up.
3 weeks ago the glow light stayed on after the engine started. I stopped twice on the way home to kill the engine and restart it.
3 hours ago my glow light mostly stayed on and I hit every green light on my commute. So I didn't stop and restart the engine. By the time I got home the battery was almost dead. Now I'm charging the battery and wondering about tomorrow.

82 300SD Heater blows warm at idle, not at speed
Re '82 300SD. Climate control switches blow air at normal rate (auto and full-on), but it only warms up at idle (e.g. stopped at traffice light). Otherwise it is cool but not cold. I replaced the thermostat; engine warms up quickly to operating temp. When fan turned off (not on auto or full on), I can feel nice warm air at side vents, so warm air seems to be in the hoses. But press the buttons and it's only cool air. Is this a monovalve issue? Something else? Thanks.

Brake lights out on 1991 560SEL
When I turn the light switch to the right to either park or full head lamps, the exterior lamp out warning lights. Also, the brake lights fail to come on when pressing the brake pedal. I replaced all three brake lamps with new lamps with no success. Might this be a brake switch problem? If so, how do I test it?

86 300SDL Turbo sunroof weatherstrip?
I R&R'd a new sunroof (Tilting)Weatherstrip.
Pretty much straight forward.......except
1: Found 2 rivets loose on back hold down bracket.
short of removing panels(trying to avoid)
any tricks to fixing? I tried a pair of needle nose vice grips, no go
2:The new strip prevents the roof from closing like the old one!
Should I "grease" it with something? If so what?
Thanks
